This is a follow up to my previous question posted here, I'm setting up a pde in 1D to simulate the convection-diffusion physics along with point sinks
pde = {Derivative[1, 0][c][t, x] +
Inactive[
Div][(-kappa).Inactive[Grad][c[t, x], {x}], {x}] + {v1}.Inactive[
Grad][c[t, x], {x}] +
Qp*RegularizedDeltaPoint[gamma, {x}, {12.4}]
I went through the documentation given here where the units of the heat source term is detailed for 1D, 2D or 3D simulation. But how the units od Qp are considered isn't very clear to me.
I would like to confirm whether the units for 1D simulation is in mol/l/s .
RegularizedDeltaPointis not a built-in function in Mma. It is introduced in the tutorial you mentioned. Please note that you have to first evaluate its definition to start solving afterwards. Further, according to its definition, this function is dimensionless by itself. Therefore, the dimension ofQpis the same as one of any other terms of the equation. For example, it is the same as the dimension of dc/dt. That is, [1/(m^3 s)] is you use the units typical in physics or [mol/(l s)] if you use chemical units. – Alexei Boulbitch Jun 21 '21 at 19:09
